Air Pump with Adjustable Air Flow Outlets for Aquarium, Fish Tank and Hydroponic Systems

Running 6 air stones for hydro and it’s just a little warm , love the manifold to adjust the air flow ,it’s makes some noise from the pumping of air but it’s normal for things to make noise as they operate , good stout pump glad I got it , don’t need 2 or 3 pumps just 1

Nice air pump. Not to noisy when all connected up. You may need to use a small hose clamp to hold the rubber outlet tube on the unit. When it warms up the tube sometimes slides off and it gets loud

To be fair, this is a good price for what you are getting. It does pump a lot of air. However its loud and gets a little bit (actually quite) hot especially when not pumping a lot of air. If you can afford it id go for a linear piston pump or something known to be quiet, however if you know the drawbacks or can put this in another room then it will probably work fine and last you years. Also dont love the cable, I feel that it could be skinnier and more flexible. The splitter seems to work well.

I use this air pump to make compost tea. For years, I have used a standard aquarium pump, which seemed to work well, but I wanted more air output, as oxygenation is a key to producing the best compost tea. I bought this one, which literally has 12 times the air output of my previous pump. I ran them both side by side with the same brand-new air stones, and WOW - there was absolutely no comparison. The maximum temperature it hit was about 126 degrees at the outlet, but the tea in my 6 gallon bucket never got above about 76 degrees. Between the huge increase in air output, and the heating up of the water, I started seeing a thick layer of foam forming on the surface of the tea hours before I normally would. Some say that these pumps are really loud. I added about an 8" length of air hose to the input to quiet it down, and while it was a little louder than my old pump, I run this thing in my garage, so it was no big deal. I'll run it in 24 hour cycles every week or two during the gardening season, so I'm thinking this will be the last air pump I'll have to buy. This seems to be well-made, and I recommend it highly.

I love these air pumps have very good quality and gives lots of air

I picked this up for my DWC hydro grow. The air flow is powerful for a 17gal tank (lots of bubbles!!).. but the NOISE! I have this pump inside my tent right now hanging from a strap to avoid vibration. Much like any air pump, noise is to be expected... but this was a bit much even fresh out of the package. It also gives off a lot of heat aka hot air bubbles and raised water temps so no good there.. I made a few adjustments the other night that seemed to work in lowering the noise and vibration. I added a longer hose leading to the 6 line manifold so the air would have some time to cool before entering water.. I also added a hosing to the pumps intake valve (right on the back of it) and extended that hose outside the tent to intake cooler air. This seemed to do the trick for all of about 48 hrs.. now the pump sounds like theres a slight rattle or metal on metal causing yet another annoying high-pitched noise to the already annoying hum/vibration sound it gives off.. I cannot rule this pump out in terms of its power.. if in an outdoor setting where the pump is free to be as noisy as it wants, this would be perfect because like i said... THE BUBBLES!!! Just keep it cool! Hot components equal hot air and raised water temps which is NO GOOD for plant roots. To sum everything up... Its noisy.. vibrates a lot.. and the components seem a bit cheaper which may require me to reverse engineer it a bit and see if i can come up with an internal fix. Until then, NEXT PUMP PLEASE!

Works very well for my 500 gallon outside koi pond in winter.

**Update** I have tried everything to help the unit run cooler and quieter. It just isn't working. It runs so hot and that makes the air coming out hot. I can't imagine an instance where this would be a good air pump. Maybe in a room kept at like 50? I have no clue. I can't use this at all with my tank. For that, I'm glad it was only 30 bucks. At least I didn't waste double that or triple that. I was pretty pumped for this to arrive. I read all the reviews and they all seemed pretty good. It arrived yesterday. I plugged it in and got it all setup. The noise level was INSANE. After 1 night of running the unit was insanely hot and the hose with the control valves came off. I reconnected the hose and 5 min later it was sliding off again. This wouldn't be a problem if the unit didn't run so hot. I could use some plumbers tape to attach the hose to the output. I worry by doing so it may overheat more. One reviewer suggested attaching a hose to the input to dampen the noise. I tried it this morning and it worked. Except the unit was already running hot and I'm afraid it may make it run even hotter. I do love that it came with a 6 output control valve. That's really handy to have. I'm going to attempt some things to see if I can get the unit to cool down before considering it a total wash. If the unit didn't run so hot and wasn't so loud I'd total give this 5 stars. I took away a star for each of those plus another because until I can figure out how to keep the unit cool I can't fix the noise level or the hose popping off the output. I will edit this if I'm able to find a way to cool the unit down and resolve the hose issue.

Excelente producto, muy compacto (no esperaba que tanto) el nivel de ruido es adecuado, lo uso para una cortadora laser y puedo trabajar durante la noche. El caudal de aire quizá no sea muy fuerte pero lo suficiente para poder trabajar limpiamente con el láser.

Esta bomba me gusta por su presión de aire que tiene, lo único que es molesto es el ruido que hace ya que tiene una entrada por donde entra el aire pero se soluciona poniéndole una manguera 50 cms y adios ruido.

Muy potente pero muy ruidosa

Funciona perfecto, y al múltiple también muy útil!

I’ve used numerous aeration pumps for my minnows but this one is the absolute best. You can’t go wrong with this pump
